SCB10 Dry‑Type Power Transformer Product Introduction
1. Product Overview
The SCB10 dry-type power transformer is a mature, widely adopted epoxy resin cast distribution transformer optimized for medium-voltage power distribution systems. Different from traditional oil-immersed transformers, this series adopts fully sealed vacuum epoxy resin casting insulation, completely eliminating oil leakage, flammability and pollution risks. Manufactured with high-quality silicon steel core and oxygen-free copper windings, the product delivers stable power transmission, low energy consumption and strong environmental adaptability. It has passed strict GB and IEC standard tests, and is a reliable power distribution solution for indoor, densely populated and high-safety requirement scenarios, widely used in industrial production, commercial construction and urban power grid upgrading projects.

3. Product Core Features
3.1 Excellent Safety Performance
The whole machine adopts flame-retardant epoxy resin integral casting structure, with no flammable insulating oil inside. It features self-extinguishing, fireproof and explosion-proof properties, which will not produce open fire or spread combustion in case of failure. The fully sealed structure avoids internal insulation aging caused by dust and moisture invasion, effectively reducing short-circuit and leakage risks, and can be safely installed in indoor load centers and closed power distribution rooms.
3.2 Low Loss and Energy Saving
Equipped with high-grade oriented silicon steel sheet core and high-purity oxygen-free copper windings, the product minimizes magnetic flux leakage and resistance loss. Compared with conventional transformer products, the no-load loss and load loss are significantly reduced, with obvious energy-saving effect during long-term continuous operation. The optimized winding structure also lowers operating noise, meeting urban and industrial low-noise environmental standards.
3.3 Strong Environmental Adaptability
The vacuum casting process makes the coil structure compact and dense, with excellent moisture-proof and anti-corrosion ability. The transformer can operate stably in high-humidity environments without pre-drying treatment before operation. The whole machine has no oil pollution, no harmful gas emission during operation, and is environmentally friendly and pollution-free, adapting to various complex indoor and semi-indoor working conditions.
3.4 Stable Operation and High Reliability
The high-voltage winding adopts multi-layer segmented cylindrical structure, and the low-voltage winding adopts foil structure with longitudinal air passages, which ensures uniform heat dissipation and strong heat resistance. It is equipped with a complete intelligent temperature detection and protection system, which can real-time monitor coil temperature and automatically start forced air cooling or overload protection. The integral casting coil has high mechanical strength and can withstand strong electrodynamic force caused by sudden short circuit, avoiding structural deformation and damage.
3.5 Simple Installation and Low Operation Cost
The dry-type structure does not need oil storage tank, oil pipeline and other auxiliary facilities, with small overall floor space and simple on-site installation procedures. The product basically realizes maintenance-free operation in daily use, eliminating regular oil detection, oil replacement and sealing inspection work of oil-immersed transformers, greatly reducing later operation and maintenance labor and material costs.
4. Application Scenarios
Thanks to its high safety, environmental protection and stable operation, SCB10 dry-type power transformer covers almost all medium-voltage indoor power distribution scenarios, and is widely recognized in multiple industries:
4.1 Commercial and Public Building Facilities
It is the preferred power distribution equipment for shopping malls, office buildings, hospitals, airports, railway stations and large exhibition centers. Its fireproof, low-noise and pollution-free features fully meet the strict safety and environmental protection requirements of densely populated public areas.
4.2 Industrial Production Sites
Suitable for manufacturing factories, chemical plants, mining enterprises and industrial parks. It can adapt to long-term continuous operation and occasional overload working conditions of industrial power consumption, and effectively avoid safety accidents caused by transformer oil leakage in industrial environments.
4.3 Urban Infrastructure and New Energy Projects
Widely used in urban power grid transformation, rail transit, tunnel engineering, water treatment projects, as well as wind power and photovoltaic power station supporting distribution systems. It ensures stable power supply for infrastructure and new energy power generation and transmission links.
4.4 High-standard Special Scenarios
It can be used in data centers, intelligent building power distribution rooms and other high-reliability power demand scenarios. Its maintenance-free and high-stability operation characteristics reduce power failure risks and ensure continuous and stable power supply for key equipment.
5. Product Maintenance and After-sales Service
5.1 Daily Maintenance Guidelines
The SCB10 dry-type transformer is designed for low maintenance, but regular simple inspection can effectively extend service life and ensure stable operation. Daily inspection mainly includes checking whether the equipment surface is clean and free of dust accumulation, whether the temperature control system operates normally, and whether the wiring terminals are loose or overheated. It is recommended to clean the surface dust and internal heat dissipation channels every 6 months to ensure smooth heat dissipation. Avoid long-term overload operation beyond the equipment rated parameters; regular overload inspection is required for AF cooling working conditions. Professional technicians shall conduct a comprehensive performance test every 2 years to check insulation performance and winding aging status.
5.2 Common Fault Handling
For minor problems such as abnormal temperature display and fan failure, users can check the line connection and fan operation status on site first. For professional faults such as insulation reduction and abnormal noise during operation, stop the machine immediately and contact the after-sales team, do not disassemble and repair by yourself to avoid safety accidents.
